Bahamas Nautical Charts on Google Maps

GeoGarage MarineMarine GeoGarage uses the Google Maps API to display about 260 nautical charts for the seas around the Bahamas, the Turks & Caicos islands, Hispaniola and the Caribbean.

The source of the charts comes from Wavey Line Publishing which has been surveying the region for many years. The charts are overlaid above the normal Google Maps tiles and a slide control allows you to adjust the transparency and compare the chart to the map tiles below.

A good example of the accuracy of the charts is the Orange Cay island, which Google Maps does not show, neither in the map view nor in satellite view.
